Doug S,
The image the instructor was trying to create involved swinging rythmically down and through. Any abrupt moves would knock the child off the swing (the clubface as the seat of a chain swing in his drawing, with the child holding on to the two parallel chains running perpendicular to the clubface).
One of the problems with instruction on magazines is that you often get opposing theories on techniques from issue to issue. I've seen tips for the same type of sand shots where the ball is played well forward on the stance, well back, and in between, with a wide open face, square, or even closed.
Unfortunately, this can be said that this is true also on the instruction tee. Personally, I once had a famous teacher tell me within a period of 30 or so days that I swung the club like a woman to "you're a big guy, why are you overswinging?" Believe me, I didn't overcook the firt lesson.
In regards to Golfweek, I would like to see a condensed John Strawn ("Driving the Green"?) series on the development of a golf course- the principals involved, how the architect is chosen, objectives of the project, the planning and permitting process (with a time-line), a generalized step-by-step description of the major components of the construction process, selection of grasses, grassing, clubshouse construction, opening, and some of the financial details. Friars Head or even Brad's home muni would be interesting subjects.
On Dr. Klein's article about the range and the course, R.T.J., II wrote a book about how understanding architecture can help you play the course. Brad's piece takes it one step further, though from the outset. Most of us would do better on the course if we practiced more like we play, particularly, hitting out of the rough, uneven lies, and devote much more time to the short game. Unfortunately, most of us are just trying to find a bit of consistency which even under the best conditions (from a perfect lie), we have an extremely hard time doing.
